To summarize, HCN emission is detected throughout most of the southern outflow lobe, from B0 to the tip of the outflow at position B2, and the brightest emission regions are associated with outflow shocks. This is consistent with the distribution of the HCN \(J\) =1–0 emission line as mapped by [1]} at \(\approx 5\)  with the Plateau de Bure Interferometer.
